Its not exactly fair. I think a fair comparison would be the pulsar vs
Bowers 805 Diamond
I hear great things about the caspian.
Have you looked at Unison research amplification yet? My dealer stocked both roksan and Unison, and pointed me to the entry level Unison Unico for the LS50's despite being able to earn bigger commission for the Roksan. He said that the LS50 benefit hugely from Class A amplification and Unison provided enough wattage in Class A to make them sing.
I eventually went for the ayre which cost a fair bit more; but just remembered our discussion on the topic.
which unison do you mean?
looks pretty good aswell.
